Visualization of angiogenesis and vasculogenesis in a late tissue radiation injury of the chest wall treated with adjuvant hyperbaric oxygen therapy using fluorescence angiography

Adjuvant radiation therapy for breast cancer treatment often involves high doses of radiation, making patients more susceptible to late radiation tissue injury (LRTI), severe complications of which involve necrosis and ulceration. Treatment of such wounds is challenging. One modality that can be utilized is hyperbaric oxygen (HBO2) therapy. However, an optimal dose and the objective evidence of its benefit in use as an adjunctive treatment modality is limited. Presented here is a case of a non-surgical candidate in which serial indocyanine green fluorescence angiography (ICGFA) was utilized to determine if it could detect changes in tissue perfusion over the course of treatment. Serial ICGFA allowed for visualization of the current phase of wound healing, angiogenesis and vasculogenesis. Future large studies should be employed to better determine the utility of serial ICGFA to improve HBO2 utilization in patients who are undergoing HBO2 as part of their course of treatment for LRTI.
